Ohau Quarry had issues with face rock getting past the skirt, resulting in significant damage to the belt. Typically the conveyor belt would be changed out every 3 months due to the re-occurrence of the impact damage, caused by the large, sharp
face rock lumps striking the belt. Entrapment damage was also being experienced, created by friction between the rock material on the belt, the belt
surface and the bottom of the skirt board when the belt sags.

The conveyor belt is the most important, and most expensive, component in the conveyor belt system. While all conveyor belts will wear out over time, to
ensure reasonable return on investment, damage should be avoided where possible.

Resolution:

First a belt support system was installed underneath the conveyor belt at the impact zone. The K-Sure® Belt Support is designed to support
the belt and provide a consistent and stable support for the troughed conveyor belt profile. It was retrofitted, utilising the existing idler frames so no
pre-engineering was required. It operates by replacing the existing wing rollers with strong, highly durable low friction polymer slider support rails. It
was simple install and will require minimal ongoing maintenance and no adjustments.

Once the belt was supported adequately, conveyor skirting can function along a flat, sag-free belt line. The K-Containment Seal is a high performance skirt
system that offers exceptional resistance to wear. The slotted system arrangement extends its service life by allowing for further ongoing adjustment after
initial installation. Since installation in July 2014 Ohau Quarry has had no issues with belt sag or belt damage and the same belt is still in operation coming up to 2 years later.

“Since the installation on the 18th Jan, the site has not had to re visit or clean the area up. So in just 6 weeks already the company has saved more than $12K. The tower is still looking clean and doesn’t look to need any attention for some time.”

Because we didn’t need to allocate any additional emergency resources to this urgent repair task, which can cost approximately $1000 a day, this problem was resolved very cost-effectively as well as quickly.”

Kinder Australia then recommended the installation of the double layered K-Skirting Seal to trap the dust particles effectively. Mounted using shallow clamps it is ideal for this confined access location. This skirt works by utilising an interior wear resistant layer of polyurethane (longer lasting than rubber skirting), but it also has an outer anti-dust integral moulding that can adapt to belt vibration and maintain the correct pressure to effectively seal the belt.

K-Sure Belt Support, with its fixed low friction slider bars instead of moving rollers, was also installed directly under the transfer point, using adjustable frames to ensure exact angles. This is the ideal combination of seal and belt support and our customer is highly delighted with the sustainable outcome of this productivity improvement.

K-Superline has now completely eliminated material build up inside the feeder chute, and so has stopped the need for any jack-hammering on site. Our customer also observed that the K-Superline® provides 50% more wear life and so is completely delighted with their investment in a correctly specified durometer of K-Superline® high performance polyurethane sheet lining. Overall, our customer is seeing major cost gains from switching to K-Superline®.

Our customer confirmed that the change over and installation was not complicated and took the anticipated 2 resources to install as part of a planned maintenance schedule. K-Skirting Seal has not disappointed and lasts approximately 12 months in regular production and suppresses the dust more effectively.

The Yallourn Power Station commenced operations in 1974 with four generating units commissioned between 1974 and 1982. Every hour 2,400 tonnes of brown coal is used to boil water into superheated steam to drive four turbine generators.

This New Zealand based customer’s core business is based around their quarry activities. They are a major supplier of quarried products to the construction industry, with raw materials extracted and processed from over 40 different sites around the country.

To resolve this problem, our customer favoured the features of K-Redi-Liner because it was lightweight in comparison to the bisalloy patches and also only needed to be bolted into place and not welded. Overall it required less labour to install which was meant that replacement costs were reduced.

Based on the results of the “Taber Test” by Excel Plas, the test conclusions confirmed that the Kinder & Co K-Superskirt® (red) polyurethane abrades less by comparison to the competitors (blue) polyurethane. The final result is further evidenced when tested at 50,000 cycles, wear index results showing 5.8 (red) compared to 25.92 (blue) or a ratio of 4.47: 1.

Our customer has confirmed that the K-Snap-Loc Dust Seal System was very easy to install “only required measuring, and some welding of the stainless unistrut and did not require knocking down of skirts and adjustment. Kinder & Co provided lots of assistance in getting quotes, drawings, supplying offcuts of material from the warehouse and working with us to get our requirements right (stainless steel unistrut instead of the standard mild steel in stock).”

Our ISO 9001 certified design and development process meant that the specification and manufacturing phase of this idea went smoothly and without error. Our customer is delighted with the final outcome.
